NWS New York, NY wrote its last area forecast discussion before the first event at Jul 29, 3:48 PM EST, 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE UPTON NY 448 PM EDT SUN JUL 29 2007 .SYNOPSIS... A WEAK QUASISTATIONARY FRONT WILL CONTINUE TO SERVE AS THE FOCUS FOR MAINLY DIURNAL CONVECTION THROUGH MON NIGHT. THE FRONT WILL FINALLY PUSH EAST OF THE AREA LATE MON NIGHT...FOLLOWED BY HIGH PRESSURE BUILDS IN FROM THE GREAT LAKES FOR TUE AND WED. THE HIGH WILL REMAIN OVER THE AREA THU AND THU NIGHT...THEN WEAKEN AS A COLD FRONT SLOWLY APPROACHES FROM FRI INTO SAT. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... EXCEPT FOR A CLUSTER OF STRONG TSTMS JUST S OF LONG ISLAND AND ANOTHER OVER NORTHERN FAIRFIELD/NEW HAVEN COUNTIES IN CT...HEAVIER ACTIVITY FROM EARLY THIS AFTERNOON HAS DIED DOWN. FLASH FLOOD WATCH WAS CANCELLED EARLIER. WILL CARRY A CHANCE POP FOR ANY REMAINING CONVECTIVE DEBRIS AND ALSO FOR SCATTERED ACTIVITY DEVELOPING ALONG THE EDGE OF THE CLOUD SHIELD MAINLY ACROSS SOUTHERN CT. WILL HAVE TO WATCH SLOW MOVING STORMS OVER SOUTHERN CT AS THEY WILL STILL BE CAPABLE OF PRODUCING VERY HEAVY RAIN IN AREAS THAT WERE IMPACTED BY FLOODING YESTERDAY. CONVECTION SHOULD DIE DOWN TONIGHT WITH LOSS OF DAYTIME HEATING...AND PATCHY FOG SHOULD FORM ESPECIALLY IN AREAS THAT RECEIVED HEAVY RAIN THE PAST TWO DAYS...MAINLY NYC METRO AND LONG ISLAND...ALSO INTERIOR SOUTHERN CT. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... QUASISTATIONARY FRONT REMAINS OVER THE AREA ON MON...SO WOULD EXPECT ANOTHER ROUND OF AFTERNOON SHOWERS/TSTMS...BUT WITH LESS HEAVY RAIN POTENTIAL AS MID LEVEL DRYING STARTS TO WORK IN...PW DECREASES TO ABOUT 1.5 INCHES...AND DEPTH OF MOIST/WARM CLOUD LAYER ALSO DECREASES. THE FRONT BEGINS TO SHIFT OFFSHORE MON NIGHT AS HIGH PRESSURE BEGINS TO NOSE IN FROM WESTERN NY/PA...SO AFTER SOME EARLY EVENING CHANCE POP MAINLY IN NYC AND COASTAL SECTIONS...DRY AND SOMEWHAT LESS HUMID CONDITIONS SHOULD RETURN BY LATER MON NIGHT AND CONTINUE INTO WED. UPPER TROUGH AXIS DOESN/T REALLY CLEAR THE AREA UNTIL TUE AFTERNOON AND IT WILL HAVE AN ACCOMPANYING SFC TROUGH REFLECTION...BUT MID LEVEL SUBSIDENCE INVERSION SHOULD PERMIT ONLY ENHANCED CU FORMATION AT WORST MAINLY NORTH/WEST OF NYC. FOR TEMPS...MAV HAS BEEN RUNNING TOO WARM OF LATE FOR MAXES AND HAVE UNDERCUT BY A COUPLE OF DEGREES...WITH NEAR NORMAL TEMPS ON MON. DOWNSLOPE FLOW SHOULD HELP NUDGE TEMPS TO SLIGHTLY ABOVE NORMAL BY TUE AFTERNOON...WITH RISING HEIGHTS/THICKNESSES KEEPING THEM SLIGHTLY ABOVE NORMAL ON WED. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... HIGH PRESSURE OVER THE REGION WILL PROVIDE FAIR AND DRY CONDITIONS WEDNESDAY NIGHT THROUGH FRIDAY MORNING. AN APPROACHING COLD FRONT WILL MOVE TOWARDS THE AREA FRIDAY AFTERNOON AND EVENING. THIS WILL BRING A CHANCE OF SHOWERS AND THUNDERSTORMS TO THE ENTIRE CWA. THE FRONT WILL PUSH INTO THE LOWER HUDSON VALLEY BY SATURDAY MORNING...THUS RESULTING IN AN ADDITIONAL THREAT OF SHOWERS ON SATURDAY AND SATURDAY NIGHT. DRIER WEATHER WILL RETURN ON SUNDAY AS THE FRONT PUSHES NORTHWARD AS A WARM FRONT AND HIGH PRESSURE BUILDS IN FROM THE SOUTHEAST. TEMPERATURES WILL BE AT OR SLIGHTLY ABOVE NORMAL THROUGH THE LONG TERM PERIOD. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... SLOW MOVING SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS MUCH OF THE TERMINALS IN THE NEW YORK CITY METRO AREA...AS WELL AS KISP. MANY OF THESE STORMS ARE PRODUCING IFR TO LOCALLY LIFR CONDITIONS. RIGHT NOW...THERE IS NOT AS MUCH CONFIDENCE WITH THE STORMS DEVELOPING ACROSS THE CONNECTICUT TERMINALS...SO INDICATED SCT035CB THROUGH THE EVENING. EXPECT THE THUNDERSTORM ACTIVITY TO DIE DOWN DURING THE EVENING...WITH AREAS OF MVFR TO IFR STRATUS AND SOME FOG DEVELOPING ONCE AGAIN NEAR THE COAST INITIALLY AND LIKELY SPREADING INLAND OVERNIGHT. WINDS WILL GENERALLY REMAIN LIGHT THOUGH THE FIRST PART OF THE DAY ON MONDAY WITH CONDITIONS IMPROVING BETWEEN 12 AND 14Z. ADDITIONAL SHOWERS AND THUNDERSTORMS MAY OCCUR ONCE AGAIN TOMORROW ALONG A NEARLY STATIONARY FRONTAL BOUNDARY. THINKING NOW IS THAT ANY SHOWERS THAT DO DEVELOP WILL START CLOSER TO 18Z AND HAVE LEFT MENTION OF IT OUT OF THE TAF WITH CONFIDENCE LOW AT THIS TIME. OUTLOOK FROM 18Z MONDAY THROUGH THURSDAY...THE GEOSTATIONARY FRONT WILL CONTINUE THE THREAT OF SHOWERS AND THUNDERSTORMS THROUGH MONDAY EVENING...WITH LOCALIZED MVFR OR IFR CONDITIONS. STRATUS/FOG WILL BE POSSIBLE AGAIN MON NIGHT INTO TUE MORNING...BUT WITH THE FRONT MOVING OFFSHORE AND NORTHERLY FLOW DEVELOPING WOULD EXPECT LESS COVERAGE THAN SAT OR SUN NIGHTS. VFR CONDITIONS WILL RETURN TUE AS WEAK HIGH PRESSURE BUILDS INTO THE REGION BEHIND THE FRONT. VFR CONTINUES WED AND THU WITH HIGH PRESSURE IN CONTROL. && .MARINE... NO FLAGS EXPECTED ON THE WATERS THROUGH THE NEXT SEVERAL DAYS WITH WINDS AROUND 10 KT OR LESS AND OCEAN WAVES MAINLY AROUND 2 FT. A STATIONARY FRONT WILL BE IN THE VICINITY THROUGH AT LEAST MONDAY NIGHT BEFORE WEAK HIGH PRESSURE SLOWLY BUILDS FROM TUESDAY THROUGH THURSDAY. THE WEAK PRESSURE GRADIENT ACROSS THE AREA WILL ALLOW FOR LOCAL DIURNAL EFFECTS TO BE PREDOMINANT...WITH GENERALLY VARIABLE OR OR OFFSHORE FLOW AT NIGHT...AND ONSHORE FLOW DURING THE DAY. WIND SPEEDS WILL BE MOSTLY 10 KT OR LESS. SEA BREEZE ONSET WILL LIKELY BE DELAYED LATER IN THE DAY TUE AND WED VS. MON DUE TO AN OPPOSING SYNOPTIC OFFSHORE FLOW. STEADY ONSHORE FLOW SHOULD RETURN AGAIN THU AND FRI AHEAD OF THE NEXT COLD FRONT...WHICH IS FCST TO MOVE OFFSHORE LATE FRI NIGHT OR SATURDAY MORNING. && .HYDROLOGY... AREAL QPF THROUGH MON NIGHT SHOULD TOTAL ABOUT 1/2 TO 3/4 INCH...BUT THERE COULD BE SOME LOCALLY HIGHER TOTALS OF UP TO 2 INCHES INTO EARLY THIS EVENING ESPECIALLY ACROSS PORTIONS OF SOUTHERN CT...AND SOME LOCALIZED TOTALS RUNNING ABOUT AN INCH ON MON. && .EQUIPMENT... THE OKX UPPER AIR SHELTER TOOK ANOTHER LIGHTNING STRIKE TODAY...THE SECOND IN ONLY A WEEK AND A HALF. IT WILL BE OTS THROUGH AT LEAST MON MORNING. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...NONE. NY...NONE. NJ...NONE. MARINE...NONE. &&
